Offensive guard Richie Incognito told police who responded to an Arizona funeral home he wanted his father’s head cut off for research purposes in the aftermath of an incident that led to the former Buffalo Bills’ player arrest Monday.

An employee at Messingers Pinnacle Peak Mortuary said in a 911 call obtained by TMZ that workers at the business were “very afraid” of Incognito.

According to the Scottsdale, Arizona police report, witnesses said Incognito walked through the funeral home punching caskets and throwing things.

“He made a gesture and said he was going to kill somebody here and said he had guns in his truck,” the employee who alerted police to the disturbance told the dispatcher. “We are just very afraid right now.”

Incognito was arrested and held on suspicion of misdemeanor charges of threats and disorderly conduct. He was related from custody Tuesday after posting a $20,000 bond.

“He’s coming back toward the office,” she told the dispatcher. “I may not be able to say anything here in a minute. … I can’t (talk) now.”

Witnesses told police that Incognito was supposed to sign cremation papers, but initially was unwilling to cooperate. He then proceeded to walk through the funeral home punching caskets and throwing things. After “making himself comfortable” in the office of one of the victims, Incognito wanted to buy flowers for the funeral and everything they had before offering them his credit card.

Witnesses said Incognito then signed cremation papers, but quickly changed his mind as he wanted his father buried and wished to view more casket options. After being shown a military casket, Incognito indicated he wanted it, but then he picked up an urn and slammed it on top of the casket.

After allegedly throwing pamphlets and patches from inside the casket, Incognito broke down while asking for his father and began crying. When Incognito was alone with Michael Wells, an employee at the funeral home, Wells stated Incognito formed a gun with his fingers, pointed it at him and said he had guns in the truck if he wanted to see.
